Filed: 2005-07-04
Granted: 2009-12-22
Abstract: A gasket and mandrel assembly, including a gasket having an annular main body portion with an anchor flange and a pipe sealing portion. The gasket is foldable between a folded position in which the pipe sealing portion is disposed substantially within the main body portion and an unfolded position in which the pipe sealing portion extends outwardly of the main body portion along its longitudinal axis. A pair of mandrels are respectively fitted on opposite sides of the folded gasket to enclose most of the gasket for casting the gasket within a wall in a concrete structure. At least one of the mandrels includes an annular outer surface aligned parallel or substantially parallel with the longitudinal axis of the gasket. Removal of the mandrels results in the cast opening in the concrete structure having a circular inner surface which is disposed parallel or substantially parallel to the longitudinal axis of the gasket and the resulting opening such that, if the gasket should fail, the gasket may be removed from the opening and an expansion-type gasket may be sealingly compressed against the opening surface with an expansion band assembly.

Title: A method for combined use of a local rtk system and a regional, wide-area, or global carrier-phase positioning system
Inventor: SHARPE RICHARD T
IPC: G01S19/48
Filed: 2004-12-15
Granted: 2014-10-28
Abstract: The present invention includes a method for a combined use of a local RTK  system and a regional, wide-area, or global differential carrier-phase positioning system (WADGPS) in which disadvantages associated with the RTK and the WADGPS navigation techniques when used separately are avoided. The method includes using a known position of a user receiver that has been stationary or using an RTK system to initialize the floating ambiguity values in the WADGPS  system when the user receiver is moving. Thereafter, the refraction~ corrected carrier-phase measurements obtained at the user GPS receiver are adjusted by including the corresponding initial floating ambiguity values and the floating ambiguity values are treated as well known (small variance) in subsequent processes to position the user receiver in the WADGPS system.

Abstract: A power buoy - tidal turbine installation - is an alternative to the conventional manner of generating power in river power stations, which is increasingly difficult to do, particularly in all those surroundings requiring high lateral, tight dams in addition to the barrage for damming up. The aim of a power buoy is to utilize the kinetic energy of flow of large quantities of water in rivers outside of the navigation channel while having minimum external diameters and maximum cross-section of flow. According to the invention, slowly running, axially impinged turbine wheels (11) having rigid or movable blades (12) are suspended in a performance-optimized flow housing (7). Said housing is protected by a box-type steel sheet jacket (6) enclosing the sides, top and bottom of the housing, and by a steel rake (16) covering the front thereof. The cavities (17) defined by the inner flow housing and the outer steel sheet jacket are subdivided into chambers and filled with water to such an extent that the power buoy stabilizes itself floating in a horizontal position, just below the water surface in order to utilize the best current.  At high water levels, the power buoy is automatically kept under water by a rise limiting rope (3) having weights (4), thereby avoiding a collision with floatage.
